Transanal Minimally Invasive Surgery Versus Endoscopic Submucosal Dissection for Rectal Lesions: A Community Hospital Experience.

To compare tumor margins and surgical outcomes between transanal minimally invasive surgery (TAMIS) and endoscopic submucosal dissection (ESD) for large or malignant rectal adenomatous polyps. Single institution retrospective analysis of patients who underwent TAMIS or ESD surgery. In total, 30 consecutive patients with similar demographics who underwent either TAMIS ( = 19) or ESD ( = 11) were included.

Comparison of polyp detection during both insertion and withdrawal versus only withdrawal of colonoscopy: A prospective randomized trial.

Background And Aims: Polyps seen and not removed during colonoscope insertion are sometimes unable to be found during withdrawal. We aimed to evaluate whether additional inspection and polypectomy during insertion increases adenoma detection rate (ADR) compared with inspection and polypectomy entirely during withdrawal.

Methods: A total of 421 patients aged ≥ 45 years and undergoing colonoscopy were prospectively randomized to receive inspection and polypectomy during both insertion and withdrawal (study group) or inspection and polypectomy entirely during withdrawal (control group).
